IMPROVED GEMENT.

I Be it known that I, Gnome WILLIAM UPHAM, of Amherst, in New Hampshire, have invented a. certain newand useful Cement is a. full, clear, and exact description thereof, reference being had to the accompanying dra'wings, and to the letters of reference marked thereon, which form a. part of this specification.

The object of my invention is to provide a suitable and effective cement, for the purpose of mending or holding the broken pieces of earthen or glass vessels together; and my cement is made of thefollowing ingredients, ,which are compounded oimixed in the proportions, or thereabouts, hereinafter described.

In making my. cement, I take one pound of shellac, two oun cessulphur, andvone 'oun'ce resin, and place them in a pot or other vessel oi boiling water, and thoroughly stir or mix'them. The cement, or the ingredients composing it, while thus undergoing the above-named process, will mix together in a. separate body from the water. When the cement is in this state, take it out of the pot and work itthoroughly by pulling or drawing it, the same as you would in making tafl'y. If, after taking it from the pot, itshould become brittle, replace it in the pot, and-again thoroughly mix it, and, while hot and soft, form it into rolls'by rolling it between two hard, smooth substances.

To use my cement, heat the article suliiciently hot to cause the cement, when rubbed against the broken edges of the article to be mended, to melt and adhere thereto; then press'the edges, coveredwith the cement, while in a soft state, firmly together, and when cool, the article can be used as before.- I

' What I claim, and desire to secure by Letters Patent, is-

The within-described cement, composed of the in proportions set forth.
